The Domestic Building Contracts Amendment Act 2025 (Amendment Act) was passed on 11 September 2025 and will make a number of changes to domestic building contracts between owners and builders, and developers and builders.
The Amendment Act introduces consumer protection amendments, many of which reflect the Government’s response to the Stage 1 and Stage 2 Reports produced by the Victorian State Government’s Building Reform Expert Panel. It also introduces a key amendment to the way the Domestic Building Contract Act 1995 (DBC Act) applies between developers and builders.
We summarise some of the key changes below, which will come into operation on a date to be proclaimed – and by no later than 1 December 2026.
The Amendment Act introduces a new ‘developer’ definition. A ‘developer’ is a person who enters into one or more contracts for or arranges for domestic building work to be carried out for the erection or construction of 2 or more homes on one or more building sites, and each of which is intended for sale or is the subject of an executed contract of sale. The definition extends to an owner of land in the same circumstances.
Part 3A will create a ‘carveout’ such that only select provisions of the DBC Act will apply to contracts between developers and builders. While the DBC Act will continue to require certain minimum terms in contracts between developers and builders, imply statutory warranties into contracts, mandate registered domestic builders carry out work, and prohibit contracting out of the Act, the bulk of the DBC Act will no longer apply to these contracts.
This will provide greater contracting freedom between developers and builders, recognising these commercial parties do not require the same restrictive protections as owners who contract with builders to build their home.
Section 3(2) of the DBC Act is an anti-avoidance provision intending to prevent aggregation of smaller domestic building contracts designed to avoid the monetary thresholds for major domestic building contracts (MDBC) and the additional legislative requirements that these contracts attract.
The amendment clarifies that if multiple domestic building contracts could be the subject of a single contract, and if they were the subject of a single contract would be a MDBC, then the contracts are taken to be a single contract for the purposes of the DBC Act.
The amendments now confirm that the following is not considered domestic building work to which the DBC Act applies:
Amendments to section 15 will (among other things):
Prior to the amendment, a building owner could not withdraw from a MDBC during the 5-day ‘cooling off period’ if they had received independent legal advice in respect of the MDBC. This restriction will be removed.
The DBC Act will provide a single variation process for variations to plans and specifications. There will no longer be a distinction between variations by a builder and variations by a building owner.
The Amendment Act will create new limits on progress payments which will depend on whether a portion of the MDBC incorporates a modern method of construction. Progress payment stages and limits on progress payments will be fixed by regulations.
New laws will be introduced in separate legislation which address modern methods of construction.
Under the new section 41, it will no longer matter whether an increase in time or contract price was reasonably foreseeable by a builder before an owner can terminate a contract. If the contract price increased by 15% or more, or the contract has not been completed within 1.5 times of the period it was meant to be completed, the building owner will be able to terminate the contract.
Amendments will address common circumstances where a dispute resolution order may be appropriate but are not currently covered by the matters listed in section 49(1)(c). The expanded circumstances now include:
A resolution order will be able to require an owner to pay an amount of money to the builder in relation to a claim or entitlement arising under the domestic building contract, and also require a builder to refund money where the builder accepted payment of an amount without first obtaining the required insurance, and where there have been significant delays in the commencement or completion of the domestic building work under the contract.
Circumstances where a certificate of conciliation can be issued to enable parties to make an application to VCAT will be expanded to include:
This change is to align with the establishment of the Building and Plumbing Commission as the single agency to administer domestic building insurance and domestic building disputes.
